. An object of the invention is to provide by sheet and causes'the paper to receive an a machine having a rotary printing form impression during several rotations of the carrying member with means for automaticylinders before the latter are separated and cally adjusting the form on the carrier bethe paper removed from the platen cylinder.

A further purpose of the different positions between impressions with invention is to arovide for varying at will reference to the supporting drive shaft for the extent to which the type form is shifted this cylinder.

Fixed to A Fig.4 is a sectionalview taken on the line the drive shaft is a pinion 5 meshing with a i+ l of Fig. 3. p gear 6 fast to shaft of the impression 'cylinder 8, the platen portion of which is indicated at 9. Gear 6 also meshes with a gear 10 secured to shaft 11 which supports the type carrying cylinder 12. The gear 16 is preferably connected with shaft 11 by being ad justably mounted upon the flange of hub 13 which is keyed to shaft 11. allowing for adjustment is to advance or retract the type carrying cylinder with respect to the platen cylinder in order to vary as a Whole the places of impression upon the paper.

In order toaccomplish the principal purpose of this invention which is to make the same impression a plurality of times in different places upon the same sheet of paper at successive rotations of the type carrying 'cylcludes a fixed pinion 15 cut in one of the bearings 16 for shaft 11, Meshing with the pinion 15 is a gear 16 journaled in a support 17 fast to shaft 11. A. carrying shaft 18 for gear 16 also carries a pinion 19 meshing with a gear 20. The gear 20 is secured to a sleeve 21 freely rotatable with reference to shaft 11 and carrying a cam 22., Since the gear 16 rolls on the fixed pinion 15, the cam 22 is rotated at a definite'ratio to cylinder 12. As

illustrated, the cam makes one rotation to each four rotations ofthe cylinder. The cam 22 cooperates with the roller 23 on a bell crank 24, one arm of which is a segment gear 25. This segment gear meshes with another segment gear 251 which is secured to the type carrying member 14 which is in the form of a yoke and includes the end plates 26 and counterweight 27.

The cam 22, Fig.3, rotates oppositely to the rotation of the type carrying cylinder 12 and at a slower rate.- Therefore since this cam operates the segment bell crank member 24 rocking it outwardly after each impression, the type holder will be adjusted with referenceto shaft 11. after eachimpressio'n.

The first two adjustments of the type carrier 14 will be in the direction of rotation of the cylinder 12 audits shaft 11 and a third adjustment will, by a-reverse motion, effect the restoring of the type carrier to its original position. This reverse motion takes place when the roller 23 rides from the high part of the cam to'the'lowvpart. A

In order to adjust the throwof cam 22 so that the angular adjustment of the type carrier 14 maybe variedto suit different sizes of paper or impression forms; ahand adjustment such as illustrated in Fig. 6 is The purpose of provided. This consists of a manually 0perated wheel 29 which is provided with an interiorly threaded hub in order to be shiftable lon itudinally along the sleeve 30 which is rigid with the ear carying sleeve 21. The sleeve 21 is provided with a pair of channels 3-1 within which are slidable the wedge members'32 havingtongues 33 engaging an annular groove 34 in the hub of wheel 29. The cam 22 is provided with inclined ways 35 which are slidingly engaged by wedge members 32 upon the adjustment of the wheel 29 and the cam therefore is shifted inwardly or outwardly from the center of shaft 11 upon an adjustment of wheel 29. The cam is guided in this adjustment by pins 36. The cam is retained in its adjusted position by means of a clamp screw 37.

For the purpose of facilitating change of forms in the im ression c linder 12 the sheet P .V a

feeding table 38 is hinged to its support at 39 as indicated in Fig. 2 and may be swung to the broken line position 40. Gauges and guides41 and 42 are provided for the paper received by table 38 as is customary. The paper is removed from the table 38 and received on the cylinder 8 as required by means of the gripping fingers 42. These fingers are operated at the proper time 'by means not fully illustrated in the drawings.

In the particular machine illustrated, the type form member 14 is adjustable on the cylinder 12. Its first position, when the fresh sheet is received by the cylinder 8 is the position 141 shown by dotted, lines in Fig. 3. Second position is the full line position 14 and the third is the dotted line position 142. When all three impressions have been made,

the fourth rotation of cylinder 12 takes place while the roller 23 is at the low part of cam 22. During this revolution of the cylinder. the printed sheet received by the delivery device 43 (Figs. land 2). Also during this fourth rotation of the cylinder 12 and the corresponding rotation of cylinder 8 the two cylinders are separated by mechanism which raises cylinder 8 so that no impression will take place at this time. For this purpose cylinder 8 is provided with journals 44 which are slightly shiftable inthe machine frame under the action of box cam 45 (Fig. 2) carried by gear 46 meshing with a pinion 48 on shaft 11. An arm 50 carries a roller at its ends for engaging the groove in the cam 45 and is also rigid within eccentric 51 fitting within themember 52 toshift the journals 44 of the impression roller 8. The impression roller 8 is normally urged toward the ceives a series of impressions one for each rotation of the impression cylinder 9 and the Figtype supporting cylinder 12, the type carrying member 14 or" the latter cylinder being shifted after each impression by means of the cam 22 as previously described in order that the impressions will each be at a different and particular location upon the sheet.

After the third impression the cylinders are separated so that at each fourth revolution of the cylinders the type form carrying cylinder 12 does not make an impression while the paper is removed from its carrying cylinder 8 and deposited into the receiver 43. Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details or" the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A rotary printing press of the class de scribed comprising a type form carrying cylinder, means for continuously rotating sa1d cylinder, a platen member cooperating with said cylinder, a type form carrying element adjustably mounted upon said cylinder, means for automatically adjusting said type form carrying element upon the cylinder between the making of successive impressions, said means for automatically adjusting the type carrying element having a varying throw, a manually operable member arranged for predetermining the extent of said throw, said means for varying the throw comprising a radially shi table cam, and the manual adjusting means comprising wedging elements for forcing the cam outwardly or drawing it inwardly.

2. A printing press of the class described comprising cooperating type carrying and platen cylinders with means for continuously rotating the same, said type carrying cylinder being provided with a type carrying formand means for automatically advancing and retracting said type carrying form angularly around the cylinder and with reference to the rotation of the cylinder as a whole.

3. A printing press of the class described comprising cooperating type carrying and platen cylinders with means for continuously rotating the same, said type carrying cylinder being provided with a type carrying form, means for automatically advancing and retracting said type carrying form with reference to the rotation of the cylinder as a whole, and means for shifting the platen cylinder after a predetermined number of rotations, said platen cylinder being provided with paper receiving and releasing means operable when the cylinders are separated.

a. A rotary printing press comprising a paper carrying platen cylinder, a cylinder having a type form carrying element thereon, means for driving said cylinders at the same peripheral speed, and means for efiecting relative angular adjustment between said type form carrying element and the platen cylinder between successive impressions whereby a sheet of paper carried by said platen cylinder will receive successive impressions upon different portions of its surface.
